The AE15-EW-S15 is a 15-watt board-mounted DC-DC converter designed for high-voltage isolated power conversion applications. It accepts a wide input voltage range of 100–1000 Vdc (10:1 ratio) and delivers a regulated 15 Vdc output at up to 1.0 A maximum current, with typical efficiency of 78% at 200 Vdc input. The converter features 4,000 Vac galvanic isolation between input and output, integrated overvoltage and output short-circuit protection, and operates reliably across an extended temperature range of -40°C to +70°C. With output ripple and noise limited to 200 mVp-p and compliance to EN 62109, RoHS, and CE standards, the AE15-EW-S15 is well-suited for industrial control systems, renewable energy applications, and high-voltage power distribution where isolation and reliability are essential.
